Pulse Cycles, Pulse Sequences, and Tissue Contrast

1989
In order to create an image in space, steps 2 and 3 of MRR must be repeated multiple times. That is, the RF pulse must be applied over and over with relaxation and signal measurement occurring after each application of the pulse. The number of such repetitions is usually on the order of 128 or 256 (or some other multiple of 64).
